A second new iPhone with a larger 5.5-inch screen has also been rumored.

When it comes to a wearable, this is a lot more uncertain. There have been plenty of rumors, and the competition is undoubtedly homing in on this market, but it is as yet unknown if this is an area that Apple is ready to enter into just yet.

It is also probably a safe bet that we will also hear more about iOS 8, along with OS X 10.10 Yosemite, along with release dates for both.

This event will be held in Apple's home city of Cupertino, California at the Flint Center for the Performing Arts, the venue where the Mac was originally unveiled back in 1984.
